Trenchless Pipe Repair Process

The Trenchless pipe repair process with Perma Liner Industries
​A non-invasive, non-disruptive approach to fixing drain pipe problems

Access
We start the process by accessing the pipe for inspection and diagnosis. The inspection is done by feeding a camera down the pipe, little to no digging is required. Ideally, the inside of the pipe is accessible through a clean out fitting. When its not, a clean out fitting can be installed onto the damaged pipe with the patent Vac-a-Tee by Permaliner.

Diagnosis
To assess the damage, a CCTV camera with pan and tilt functions is fed down the pipe. We’re looking for the location and the size of the hole, and any roots or objects obstructing the pipe. Debris can be cleared with a high pressure jet unit or cut away with a mechanical cutter to clear the pipe for repairs.
Prepping the Materials
In preparation for the Cured-In-Place-Piping installation, we roll out and cut to length the liner that will form the new pipe, and measure out the proper amount of the 2 part resin mixes.

Installation
The actual installation is done by inverting the liner into the pipe using the inversion machine. The liner is pressurized to conform to the existing pipe and mold the resin into the desired shape. The resin migrates into any voids in the line, filling crack and holes.

Cure
The final step is to cure the resin, forming a brand new, fully functional pipe inside the existing line that will last at least 60 years. Ambient curing takes about 3 hours, a process that can be reduced to ~20 minutes with steam curing.

Perma Liner’s systems effectively and efficiently repair pipes of all materials, since the process forms a brand new pipe inside the existing tunnel. With versatile materials and equipment that make the Trenchless repair system adaptable to almost all conditions, Waeco is prepared to rescue homes and businesses from drain pipe problems in a single day’s work, without excavating your yard or parking lot.
